ABSTRACT:
A level-sensing collar is rigidly mounted on a vertical tubular nozzle of a container-filling machine. The collar is located a predetermined distance above the nozzle outlet and is provided in its bottom with an upwardly extending recess encircling the nozzle. The collar also has a plurality of circumferentially spaced openings connecting its recess with the lower ends of air tubes that extend up along the nozzle to air-receiving means that first receives high pressure air to blow down out of the collar recess any product that has accumulated in it and then receives low pressure air for delivery to the collar recess so that when the level of the product in a surrounding container rises high enough to close the recess the air pressure in the tubes will built up and shut off the delivery of the product to the container.
